Design of Data Transfer Terminal Unit Based on GPRS

Lixin Song

Abstract

The characteristics of GPRS(General Packet Radio Service) technology in data transmission are introduced in this paper.Based on analyses of the technology and principle about the GPRS,the design of data transfer terminal unit is completed.In the design,the SPCE061A MCU is the central processing unit,and the SIM300 Module is used.Finally the implementation of the hardware and software of the data transfer terminal unit is presented.Convenience and low cost are main superiorities of this unit.
